Blazor WebAssembly C#调用DevOps REST API创建项目遇执行异常

在Blazor WebAssembly的C#代码中调用REST API在DevOps创建新项目时，函数最后一行Microsoft.VisualStudio.Services.Operations.Operation operation = await operationsHttpClient.GetOperation(resultId);始终无法执行，且无任何错误抛出。已确认PAT和URI正确，相关代码如下：

public async Task PushProjectToDevOps(string pat, ProjectDTO project)
{
    TeamProject teamProject = new();
    teamProject.Name = project.Name;
    teamProject.Description = project.Description;
    VssBasicCredential credentials = new VssBasicCredential("", pat);
    var connection = new VssConnection(uri, credentials);

    OperationsHttpClient operationsHttpClient = connection.GetClient<OperationsHttpClient>();

    using (ProjectHttpClient projectHttpClient = new ProjectHttpClient(uri, credentials))
    {
        var resultId = projectHttpClient.QueueCreateProject(teamProject).Result.Id;

        Microsoft.VisualStudio.Services.Operations.Operation operation = await operationsHttpClient.GetOperation(resultId);
    }
}

• 禁止同步异步混用：代码中用.Result同步调用QueueCreateProject，在Blazor WebAssembly单线程环境下会造成死锁，导致后续代码无法执行。改成异步调用：

  var createResult = await projectHttpClient.QueueCreateProject(teamProject);
  var resultId = createResult.Id;
  

• 统一客户端实例化方式：ProjectHttpClient单独实例化，和OperationsHttpClient的连接上下文不一致，建议通过VssConnection统一获取客户端：

  var projectHttpClient = connection.GetClient<ProjectHttpClient>();
  // 去掉using，VssConnection会管理客户端生命周期
  

• 添加异常捕获与日志：隐藏的异常可能导致代码中断，添加捕获逻辑排查问题：

  try
  {
      var createResult = await projectHttpClient.QueueCreateProject(teamProject);
      var resultId = createResult.Id;
      var operation = await operationsHttpClient.GetOperation(resultId);
  }
  catch (Exception ex)
  {
      Console.WriteLine($"异常信息：{ex.Message}");
      if (ex is AggregateException aggEx)
      {
          foreach (var innerEx in aggEx.InnerExceptions)
          {
              Console.WriteLine($"内部异常：{innerEx.Message}");
          }
      }
      throw;
  }
  

• 校验操作ID有效性：在获取resultId后打印日志，确认ID不为空或无效值，排除ID本身的问题。
• 检查跨域配置：Blazor WASM运行在浏览器中，需确认DevOps API已允许应用域名的跨域请求，查看浏览器控制台网络标签页是否有跨域错误。
